What belief did Protagoras hold regarding perception?

Protagoras, a pre-Socratic philosopher known for his relativistic views, famously asserted that "Man is the measure of all things." This phrase encapsulates his belief that perception is inherently subjective; individuals perceive the world uniquely based on their experiences, biases, and contexts. Therefore, what one person perceives may not be the same as what another perceives, emphasizing that there is no absolute truth in perception. This relativistic viewpoint underlines the idea that knowledge and understanding are limited to individual perspectives. Protagoras's stance promotes the understanding that reality can differ based on personal interpretation, which aligns with the correctness of the belief that perception is subjective.
